Filter Out Iron, Sulfur, and Manganese

Does your water smell like rotten eggs? Do your sinks & toilets have orange staining? You and your family deserve the best quality water and expect that it be delivered at each faucet whenever needed.

RKIN Filter System is the answer to your problem with water to reduce Iron, Sulfur, and Manganese.

Softer Skin & Healthier Hair

Eliminate contaminants in the water that can be harmful to your body. By filtering out iron, sulfur, and manganese, you can avoid the negative effects of these elements, promoting softer skin and healthier hair.

Why Use a Water Softener

The mineral build-up, or scale, can occur in plumbing and household appliances when your water is hard. Solid deposits of calcium carbonate can form when hard water is heated. This scale can reduce the life of appliances, raise the cost of heating your water and clog pipes. Long-term movement of hard water through a pipe results in scale buildup. This can gradually close up the pipe and lower your water pressure.

Prevent Hardness Build-up

Extend the life of your plumbing and household appliances by preventing scale build-up. Appliances that use water will last longer and run better. Why? Because water heaters, washing machines, and dishwashers using hard water can wear out 30% faster.

Independent laboratory testing

Test once and ensure you are purchasing the proper water system for your home.

A water test by a certified independent laboratory will help you determine exactly which water issues are present and identify the proper equipment needed to treat them. For most people, on well water Metals and Minerals test is sufficient. If you notice yellow coloration of water or staining, a tannins test is also required.

Access easy sampling, certified laboratories, and unbiased expert advice with SimpleLab. It's advanced water testing made easy. Our easy-to-read, professional water report provides a complete picture of your water quality.

We will even credit the water test cost towards your combo well water system purchase!

How often does the RKIN salt-based water softener require salt replenishment?

RKIN CS series salt-based water softeners proactively monitor water usage and regenerate when needed. This "metered" approach ensures maximum efficiency for salt and water usage.

The exact regeneration schedule and salt replenishment requirement will depend on your water hardness and total household water use.

The water softener will regenerate at least once every seven days to keep the media within the system in a top-performing state.

Does the RKIN Whole House Water Filter System add anything to the water?

No, it doesn't. The RKIN Whole House Water Filter System filters out impurities from your water, eliminating unwanted iron, sulfur, and manganese without the use of any chemicals. It provides clean, filtered water from every faucet of your home.

What can I do with the mobile app?

Legacy View mobile app makes setting up and monitoring your RKIN Water Softener easier than ever. A free download of the phone app is available for your iPhone or Android device.

Conveniently view all valve settings and status
View estimated salt remaining(water softener only)
Easily change valve settings

Graphically view water usage history

Do I have to use the mobile app?

No, the mobile app is not required. All the settings can be updated directly from the Water System's control board.

The mobile app does make the setup quick and easy.

The Bluetooth module on the valve can be disabled, and the mobile app can be deleted from the phone after the initial setup.
